This is description of Limit Break right? Limit Break - A skill to go over one's limits; amplifying their power by three times one's basic stats, but this power comes with a rebound - once used the user will be heavily fatigued. Using it for long periods of time will damage the user's body. Overload/Overdrive - A skill greater than "Limit Break" - it multiplies the abilities of the user by 5 times with more damage recoil to the user than the normal "Limit Break". War Demon - A derivative skill of "Limit Break" which reinforces his body using his mana, no matter how broken up his body is. As a result, Alex can continue fighting for multiple days with numerous injuries without rest.
